Troubleshooting, as a rule of thumb, is basically a process of elimination. In a
complex electrical system with many components, it can be sometimes difficult to
determine exactly why the system is not working the way you wanted it to. If you only
have one DVR system, the maintenance person may need to understand the entire DVR
system to logically deduce the exact cause of the problem. If you have more than one
system installed on your vehicles, then troubleshooting is a lot easier. A good way to
discover which part of the system is not operating properly is to swap components and
see which component the problem follows. For example, if you suspect there may be a
problem with a hard drive, you can put the hard drive into a different DVR and if the
drive works in that DVR then you know it is not the drive.
In most cases we can find that the reason the DVR is not doing what the end user
wants it to, is because the DVR is not configured to operate in that manner. A good
example of this would be if the DVR was placed in Timer Mode, and the operator wanted
the DVR to go on and off with the ignition.
